Webdriver - 無限頁面加載提交

Question

我正在測試登錄頁面。在某些時候（間歇性地讀取）加載主頁需要無限的時間。在這種情況下，下面的命令無法完成 -

driver.findElement(By.id("Login")).submit(); 

我知道隱式&明確等待的。 這些等待只爲findElement或DOM相關的行動，但不服從命令（（參考文獻都適用：https://sqa.stackexchange.com/questions/2606/what-is-seleniums-default-timeout-for-page-loading）

調試日誌跟蹤 -

基本上DefaultClientConnection沒有收到200 OK &的命令只是掛起

尋找解決方案關閉瀏覽器以防瀏覽器沒有響應提交命令等待之後g一段特定的時間。

Answer 1

我猜ID「登錄」是一種形式。

您可以改爲選擇表單的提交按鈕（假設存在）並在按鈕上調用.click（），而不是在窗體上調用.submit（）？

然後你應該可以使用隱式或顯式等待。

編輯：

提交表格後，您可以進行自定義的方法來等待響應，並超時，如果必要的話後，要關閉瀏覽器。

 int tryCount = 0; 
     boolean desiredResponseReceived = false; 
     while (desiredResponseReceived == false && tryCount < 20) { 
      String statusText = (String) js.executeScript("return xhr.statusText;"); 
      if (statusText.indexOf("200") != -1) { 
       desiredResponseReceived = true; 
      } 
      else { 
       Thread.sleep(250); 
       tryCount++; 
      } 
     } 

     if (desiredResponseReceived == false) { 
      driver.quit(); 
     } 

正如所寫的，如果在5秒內沒有在xhr響應中出現「200」，該方法將關閉瀏覽器。 （因爲它每隔250毫秒檢查20次，最終在達到if (desiredResponseReceived == false)之前檢查並關閉瀏覽器）。
